 Trip highlights:

  • examination and discussion of the northern portion of the Marysvale volcanic pile
  • newly mapped Oligocene volcanic intrusions
  • discussion of the contested Sanpete-Sevier Valley anticline and associated structures including the surface structure over the Covenant oil field
  • contorted Middle Jurassic Arapien and Twist Gulch Formations
  • Paleogene sedimentary strata including the Flagstaff, Colton, Green River, Crazy Hollow, Aurora and Dipping Vat Formations
  • Silicified beds of the Crazy Hollow Formation?

The purpose of the review is to give the public and local government officials an opportunity to learn about new geologic research in their district, and to give geologists and others an opportunity to critique the map before it is published.
